Abstract
The variation of the superconducting transition temperature () with hydrostatic pressure up to 23.7 kbar is reported for eleven ternary silicides and germanides with the -type structure. Most of these compounds display a modest linear depression of with pressure (/dp∼ K/bar); however, two materials, and , undergo a discontinuous transformation to a state with a significantly higher above a critical pressure of about 20 kbar. For , the pressure-enhanced of 9.12 K is the highest transition temperature reported for this class of compounds.
